Recreational tournament style paintball on fields that may or may not be in good condition. Typically its run like a practice but less formal. Players from random teams will get together to forum one team.

Tom: Hey Carl there is no practice this week right?
Carl: Nah man everyones got shit to do.
Tom: What to go hit up some Street Ball then?

Streetball is basketball, but with certain rules relaxed. People do not resort to calling pussy fouls. Teams are usually 3 a side, and played on one basket. Over time, the game has become assosiated with tricks and difficult dunks, but this is only in conjunction with making the basket

Guy 1: Wanna go play some basketball?

Guy 2: No thanks, its too structured. I wouldnt mind a game of streetball tho.

A sport involving a basketball, a basketball court and a basketball net although the rules of basketball are thrown out. The idea of the game is to show the punk ass bitch gaurding you who's better. If having to bounce the ball of the back of his head will achieve this goal then go for it.
